For a test of a single bit you can do a logical and on a copy of the byte or use NRK. For testing multiple bits you can execute a TM.

I have something like this : A DC X'1C'B DC X'08' TM A,x'08' JO X But instead of using x'08', i need to use the variable B in the comparison, because the content of B may change.So, i would need something like this: TM A,B How can i do that ? Thanks in advance.
